This document contains information from Dr. Anas Sahle regarding chest CT cases and a collicum exam. For the chest CT cases, there are images and descriptions of findings for HRCT-1, including linear opacities, centrilobular nodules, tree-in-bud patterns and bronchial wall thickening. After treatment, there is marked resolution of the findings. Histology shows a bronchiole with lymphoid follicles, consistent with chronic follicular bronchiolitis. The collicum exam contains 12 multiple choice questions on various respiratory topics like teratomas, Hounsfield units, findings associated with ARDS, and appropriate treatments for conditions like lung abscesses.

3. HRCT-1

4. HRCT-1
• What is the major abnormality in this case?
• a) Linear opacities
• b) Nodules
• c) Consolidation
• d) Ground-glass opacity

5. HRCT-1
• 2. What is the distribution of the
abnormalities?
• a) Bronchial/bronchiolar
• b) Interlobular septal
• c) Centrilobular
• d) Pleural

6. HRCT-1
• Find a row of centrilobular nodules within 5
mm of the pleura in the right lung.
• Find 2 rosettes in the right lung.
• Find a tree-in-bud pattern in the right lung.
• Find bronchial wall thickening in longitudinal
or cross-section in the right lung (one of each
is marked).

7. HRCT-1

9. • This slice of lung with bronchopneumonia
shows a pattern similar to that shown in the
HRCT image above.
• Find a row of subpleural centrilobular
nodules.
• Find rosettes (2 are marked).
• Find tree-in-bud patterns (1 is marked).

11. After treatment.

12. Q
• What changes have occurred after therapy?

13. Answer
Marked resolution of
diffuse centrilobular nodules
tree-in-bud changes
bronchial/bronchiolar wall thickening

14. HISTOLOGY

15. DIAGNOSIS?
• 1. What type of airway is this?
• a) Bronchus
• b) Bronchiole

16. DIAGNOSIS?
• 1. What type of airway is this?
• a) Bronchus
• b) Bronchiole
This airway is a bronchiole because it lacks
cartilage.

17. DIAGNOSIS?
• 1. What type of airway is this?
• a) Bronchus
• b) Bronchiole
This airway is a bronchiole because it lacks cartilage.
• 2. What are the collections of cells in the thickened
airway interstitium?
• a) Lymphoid infiltrates
• b) Lymphoid follicles
• c) Infiltrates of PMNs
• What is the histologic diagnosis?

18. DIAGNOSIS?
• 1. What type of airway is this?
• a) Bronchus
• b) Bronchiole
This airway is a bronchiole because it lacks cartilage.
• 2. What are the collections of cells in the thickened
airway interstitium?
• a) Lymphoid infiltrates
• b) Lymphoid follicles
• c) Infiltrates of PMNs
• What is the histologic diagnosis?
• Chronic follicular bronchiolitis

19. DIAGNOSIS?
Diffuse bronchitis and bronchiolitis

20. Summary
diagnostic features of diffuse
bronchitis/bronchiolitis on HRCT
• Diffuse well- and poorly-defined centrilobular
nodules
• Tree-in-bud pattern
• Thickening of bronchial walls
• ± Patchy pneumonic consolidation
